LIX is an incredibly small 3D-printing pen created by Ismail Baran, Anton Suvorov, and Delphine Eloïse Wood that can doodle in the air to create designs out of plastic that’s typically featured in regular 3D printers. The aluminum pen is powered via a USB 3.0 port and uses ABS/PLA filaments that are heated thanks to a hot-end nozzle and then cooled to produce 3D structures. LIX is currently raising funds via a Kickstarter crowdfunding campaign.
